I'm making notes from my textbook to convert to my notebook and wanted to make sure that what I have is right.
#Checking my cheat sheet

Fractions are simple the top number is the numerator and the bottom is the denominator when you simplify you find what both numbers share and divide them to make it smaller when adding or subtracting you need the same denominator so you change both fractions to match then add or subtract the top numbers and keep the bottom the same when multiplying you just multiply top with top and bottom with bottom and you can simplify before or after when dividing you flip the second fraction and multiply and if you have a whole number turn it into a fraction like 4 becomes 4 over 1 and always simplify at the end

This looks correct and thorough, well done. You have a typo in "Numerator", but the math is correct 😉👍

That's my emotional support typo.

Fractions are simple when you know your stuff.
strong pivot
Then you should keep it (the typo) 😂👍
night phoenix
I do not hence the cheat sheet.
strong pivot
With enough practice you will get to the point where you no longer need the sheet at all, but it's a very well made sheet.
You probably learned something while making it too.

Stuff is hard when you are not yet proficient in it, regardless of how easy it can feel afterwards.

Shaw?

Oh 😅 Never seen it written 😅🫣

I'm here if you need anything else checked 👍

Danke
Just a fact check.
Say I have like 1/4 times 8 that's just find a quarter of 8 right? And if I divide I'd take the reciprocal of 8 to 1/8 then multiply across right?
strong pivot
Yup

You from Germany? Ich spreche ein bisschen Deutch 😉 Very limited vocabulary though, so best to keep the conversation in English 😅

Aha 👍
Do you want those other pages you are writing checked when they're ready too? Or are you ready to mark your question as solved?
Use .close to mark as solved, or you can @ me when you want more help and I'll be back. @night phoenix
night phoenix
I'll make a new help when I got all my sheets done and I'll @ you ok?
strong pivot
Ok

Also, people usually say "greatest common division" or GCD, not "least common division" or LCD as you write it.

The book said lcd so that's what I did.

Also, wdym by PEMDAS for simplifying fraction. PEMDAS is just a convention about how to read an expression. Specifically, it's about where are the "invisible brackets"

Yeah right. GCD and LCM. Greatest common divisior and least common multiple. Easy to mix them up.

For example, the expression 2 + 3 * 4 + 5 is read as if it's written 2 + (3 * 4) + 5

Might have been lcm?

There is also no requirement to fully simplify the numerator and the denominator before simplifying the whole fraction. If you think like this, you will get stumped hard when you learn polynomials (i.e. when dealing with rational function, very common type of function that you get to deal with when you later learn limits)
You just have to keep in mind that to simply fractions, you divide both numerator and denominator with their GCD, and you can preemptively cross out common factors.
strong pivot
Ok. Both GCD and LCM are helpful when working with fractions, so I'm not sure which one your note refers to.
strong pivot
I'd use LCM for that.
